Question 1 of 31048

What is the minimum number of portable fire extinguishers required on board a 45-foot uninspected towing vessel built in 2017 and having a fixed fire system on board?

🔍 Key Concepts

• 46 CFR Subchapter C requirements for uninspected towing vessels • Fire protection table for vessels 26 feet or more but less than 65 feet • Effect of having a fixed fire extinguishing system in the machinery space on the number/size of required portable extinguishers

💭 Think About

• First, decide which CFR table applies to a 45-foot uninspected towing vessel and confirm the fire extinguisher classification column to use • Think about how the presence of a fixed fire system in the machinery space changes the number and/or rating of required portable extinguishers compared to a vessel without one • Compare the baseline requirement (no fixed system) to the reduced requirement when a fixed system is installed, then match that to one of the listed options

✅ Before You Answer

• Verify you are looking at uninspected towing vessel requirements, not inspected or passenger vessel tables • Confirm the length category that includes 45 feet and see the corresponding number of 5‑B extinguishers both with and without a fixed system • Make sure you understand that a fixed system in the machinery space can allow substitution for one 5‑B portable extinguisher in the table, and apply that correctly to this length of vessel
